Another 45 min Substance Painter test. This time instead of using Maya to remesh, I used MeshLab's Quadric Edge Decimation filter. Then did some minor clean up work, and auto uved in Maya. Then finally imported both meshes into SP and added several smart materials and then polished it off with a quick paint over.
